Major victims of asbestos had been workers in general industries, transport, building and shipyards. It was an awful discovery that transformed this magic mineral into a killer dust. Has been used extensively as building material, especially from 1950s to 1980s1…

An estimated 1.3 million employees in the construction and general industry are at risk. No doubt, we are exposed to a certain level of asbestos material all the time. Asbestos, in the finished form, does not pose any health hazard. Remodelling, repair, maintenance, demolition, sale and transport combined with rough handling all can release these deadly fibres into water or air2. Inhalation of these fibres for a continuous period could be extremely dangerous. . Chrysotile, a fibrous mineral which neither burns nor rots, flexible with maximum tensile strength, extremely useful, lightweight, can create a formidable surface mixed with cementing materials, could be used as high temperature seals and gaskets, known over 2000 years, first mined in Russia, Italy and Canada. Old products, unlike today's improved technological ones, crumbled easily under pressure and released more harmful fibres. All these fibres are non-inflammable
Asbestos is a highly emotive topic with two shrill schools of thought, one saying that asbestos should be banned; another arguing that asbestos of today would not be a killer. European Union (EU)3 and the United Kingdom (UK)4 both argue that asbestos is carcinogenic and targets multiple organs of the dust inhaler. According to their rules all types of asbestos are harmful and there is no safe level of exposure and the weight of evidence to support this is incontrovertible and historical. It is impossible to control the exposure to asbestos in workplace and hence, alternative products must be used. Asbestos should be discarded as a harmful object and should be banned, to protect public health. This risk-based approach depends on the fact that there is no identified lower exposure limit to which workers can be safely exposed.5 In spite of the overwhelming medical reports, there is little scientific research evidence to back this viewpoint and the entire exercise seems to be more of a public emotional grandstand. Asbestos is heat resistant and is used in a wide variety of industrial and domestic appliances and this makes it particularly difficult to avoid it completely. It is a mineral fibre used in a variety of building construction materials for insulation and it is also a fire-retardant. The necessity of completely stopping the usage too is questioned by many scientists.

Asbestos is a pale-colored, fibrous mineral formation with a storied history. It is perhaps the fact that it was once so popular as a building material that colors our current sense of urgency regarding its toxicity. Asbestos was known to the ancient world, named in a variety of sources as a material useful for lamp wick's, fireproof clothing, and in buildings as a source for fireproof curtains.
Also, included in this letter are advices, and controls that you may undertake to solve your asbestos problem. Asbestos and Its Common Uses First, I would like to discuss to you the general information on asbestos. According to the Agency for Toxic Substance and Disease Registry [ATSDR] (2001), asbestos is a common term that often refers to anthophyllite, tremolite, actinolite, amosite, crocidolite, and chrysotile.
The author explains that with the discovery of peculiar characteristics of water, aside from relying on the magnetic field generated by various molecules in cells, the additional characteristics of particle diffusion in living cells were able to contribute to the greater advancement of the use of MRI.
The author explains that there are 6 asbestos minerals and these are Actinolite, Amosite, Anthophyllite, Crocidolite, Chrysotile, and the deadliest Tremolite. When these tiny dust-like particles at about 1 micron in diameter are inhaled, they penetrate the lung tissue and stay permanently; when accumulated, they eventually scar the lungs.
Consequently, asbestos can be found in almost all aspects of people's lives. In the US, the government usually recognizes certain varieties of minerals as asbestos products and these include; crocidolite, amosite, chrysolite, anthophyllite, actinolite and tremolite.
Amosite and crocidolite are iron-rich fibrous silicates and have really no economic importance, and they belong to a group of 50 other iron-rich asbestos minerals (Bandli and Gunter, 2006, 949-962).
Asbestos induces disease in man has been confirmed through clinical observations, pathological assessments of tissue, and epidemiological data obtained from exposed cohorts.
